Abstract

The invention belongs to the advanced compound materials science domain. Publicized a kind of continual textile fiber enhancement to gather the fragrant ether sulphone alkone (PPESK, when its S / K=0 was PPEK; When S / K=1 is the PPES advanced compound material preparation) its characteristic is gathers the fragrant ether sulphone alkone (PPES) to dissolve in N, the N- dimethyl acetamide (DMAc) either the N- methyl pyrrolidone (NMP) or in the chloroform or their component solvent, compounds 20%-40% (quality content) the PPESK solution, separately soaks the continual glass fiber, the carbon fiber, the fragrant black silk ribbon textile fiber, the system results in the preliminary dip material piece. Twines the preliminary dip thin slice after the textile fiber or pulls crowds takes shape the craft system type, carries on the thermo-compression to take shape, its main craft parameter as follows: Cold-press: 25~35MPa / 2~10min+ preheating: 380deg.C / 40~90min+ thermo-compression: 20~40MPa / 380deg.C / 40~90min+ cooling: 100deg.C / natural cooling + drawing of patterns. The invention effect and the profit are causes the continual textile fiber high performance thermosplastic tree fatty group compound material solution preliminary dip to take shape the craft to become possibly, has the practical value regarding the impetus advanced compound material development and the development in the astronautics aviation domain application.

Description

technical field [0001] The invention belongs to the field of advanced composite material science and technology. Disclosed is the preparation of a class of continuous fiber reinforced polyarylethersulfoneketone (PPESK for short, whose S / K is adjustable, that is, PPEK when S / K=0; PPES) when S / K=1) advanced composite materials. In particular, it relates to the preparation of continuous fiber reinforced polyarylether sulfone ketone (PPESK) advanced composite materials by solution prepreg winding and pultrusion molding process. Background technique [0002] Continuous fiber-reinforced high-performance thermoplastic composites have excellent chemical resistance, radiation resistance and electrical properties, short production cycle, high production efficiency, repeatable or secondary molding, and overcome the poor toughness and low elongation at break of thermosetting composite materials, which are easy to The shortcoming of early stress cracking; it also makes up for the short-...
