It is too early to say, for instance, whether the process, so far tried on polyacrylonitrile carbon fibres, will be equally effective on pitch fibres, though Pickering sees no reason why it should not be. It has been tested on cured and uncured material (about 40% of long-fibre pre-impregnated material comprises uncured manufacturing offcuts) and proved successful on both, but it has not yet been tested against samples of sandwich or bonded structure.

也许目前还言之过早，例如，聚丙烯腈碳纤维的回收过程，是否对沥青纤维同样有效，虽然皮克林称，还找不出不可以的理由；另外，对固化/未固化材料（约40％的未固化长纤维预浸渍材料）的分别实验均证明成功，但尚未对夹芯结构或粘结结构样品进行测试。
